13 Weeks Pregnant With Twins: Belly, Ultrasound, Size & Symptoms
When you’re 13 weeks pregnant with twins, you’re in the second trimester of your pregnancy. The risk of miscarriage has dropped significantly, and you may begin to feel more energetic.
Pregnancy diet, nutrition & prenatal vitamins
Take an iron supplement if your doctor or midwife recommends it. Be aware that constipation can be a side effect of using iron supplements. It also increases the risk of constipation to take medication for acid reflux and heartburn. There are some natural things you can do to get your stomach going:
- Exercise at least half an hour a day
- Drink plenty of water
- Eat foods high in fiber. It can be vegetables, fruits or foods with wholegrain
- Prunes and figs are loaded with fiber and are great at relieving constipation
Baby size & development
Your babies are approximately 7,5 cm (2.95 inches) from head to rump when you’re 13 weeks pregnant with twins. All your children’s organs are developed but are still maturing. At the end of this week, lines can be spotted on their fingertips. These will develop into fingerprints. All the bones still consist of cartilage but will continuously be replaced by harder bone.

Many women suffering from morning sickness feel the nausea subsiding in the second trimester. Your hormone levels are evening out as your placenta becomes fully operational and starts to create the required progesterone. You may feel more energetic and have more energy during the day. When you reach your second trimester, the risk of miscarriage drops significantly. This fact makes many women feel a lot more confident and secure about their pregnancy. However, for a woman carrying twins it can be a little different. Many women are aware that their pregnancies are higher-risk and have a lot of knowledge about what potentially can go wrong. Try to keep in mind that the great majority of twin pregnancies result in healthy babies. However, don’t hesitate to contact your doctor or midwife if you’re worried about any signals you’re body might be sending you.
Ultrasound scans at 13 weeks pregnant with twins
If you haven’t had one already, you are going to have your dating scan soon. It’s important that your sonographer looks for your twins chorionicity. Chorionicity relates to whether or not your twins share a placenta. Fraternal twins always have separate placentas. About 1/3 of identical twins have separate placentas as well. The rest share a placenta. Twins, who share a placenta, are more at risk of complications during pregnancy and birth. Chorionicity is determined by the use of ultrasound. If the sonographer isn’t able to determine chorionicity, you should be referred to a maternal-fetal medicine (MFM) specialist.
